VACUUM GASOLENE-PUMP.

Specification of Letters Patent.

Patented Aug. 31, 1920.

Application filed December 23, 1918. Serial No. 268,022.

To all whom it may concern Be it known that I, GEORGE E. FRIEsEN,

a citizen of the United States, residing at North Yakima, in the'county of Yakima and State of Washington, have invented a new and useful Vacuum Gasolene-lump, of which the following is a spec fication.

The device forming the sub ect.matter of this application is adapted to be employed for dispensing gasolene and like liquids, and one object of the invention is to provide novel means whereby the supply of liquid to a measuring tank, the amount of liquid delivered from-the tank, and the suction applied to the tank, may be controlled simultaneously.

Another object of the invention is to provide a device of the class mentioned wherein the purchaser can ascertain by inspect on that an honest transaction has been effected, as to the amount of'liquid delivered.

A further object of the invention is to improve the means for controlling the suc-' tion which is applied to the tank.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to'which the present invention appertains. v

With the above and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that, within the scope of what is claimed, changes in the precise embodiment of the invention shown can be made without departing" from I the spirit of the invention.

I In the accompanying drawings Figure 1 shows in longitudinal section, a portion of a structure embodying the improvements hereinafter alluded to; Fig. 2 is a top plan showing the sleeve which is placed about the tank, at times; Fig. 3 is'a top plan wherein parts are omitted; Fig. 4 is an elevation showing the complete structure; and Fig. 5 is a sectional 'detailillus trating the valves.

In carrying out the invention there is provided a support, which may be variously constructed. The support may include a base 1 on which rests a tubularpedestal 2.

The pedestal 2 supports a tank 3 including a bottom 4, a top 5, a'transparent shell 6 located between the top and the bottom,

gaskets 7' interposed between the ends of the top, on the one hand, and the bottom 4: and the top 5 on the other hand, and draw bolts 8 connecting thetop and the-bottom. The shell 6 of the tank is marked as shown at 9, to indicate the capacity of the tank.

When the structure is not in use, a protecting sleeve 10, shown in Fig. 2 and in Fig. 1, may be locked about the shell 6, the ends of the sleeve being engaged by the top 5 and by the bottom 4. Thesleeve 10 preferably consists of h in'gedly connected, parts, as shown in Fig. 2. i

The top 5 carries ahousing 11. A bracket- 12 extends across the bottom of the housing 11 and is terminally securedto the top 5. A plunger 14 is mounted to reciprocate in the bracket 12 and constitutesa portion of pipe 19 within the pedestal 2 and is provided with a lateral air inlet 22. A threeway valve 21 is journaled for rotation in the casing 20 and may be variously constructed. The three-way valve 21 ma have a straight passage 23 and a curve passage 24. v

The numeral 25 denotes a combined supply and discharge pipe connected at its upper end with the. bottom 4 of the tank 3 andcommunicating with the tank. A casing 26 is interposed in the pipe 25 and carries a lateral pipe 27 supplied with a hand valve 28. A hose 29 is connected to the pipe 27. The pedestal 2 is provided with a swinging door 30, and .at the'lower edge of the door, a notch .31 is formed'in the pedestal 2. "The free end of the hose 29 may be mounted in the notch 31, when the hose is not in use, and, when'desi-red, practically the entire length of. the hose may be housed in the pedestal 2. A valve 40' is journaled in the casing 26 and is provided with a'straight passage 32 and with a curved passage 33.

An arm 34 is secured to'the valve 40, the

'35.- A connection 36 is supplied, the same valve 21being operated by means of an arm which is accessible from the outside of thepedestal 2.

Let it be supposed that the valves 40 and 21 areoarranged as shown in Fig 5. Then, the air inlet 22 is closed by the valve 21, the passage 23 communicating with the suction pipe 19. Similarly, the pipe 27 and the dispensing hose 29 are closed by the valve 40, the passage 32 being in communication with the parts of the pipe 25. If suction'is applied by Way of the pipe 19, to the tank 3, gasolene or other liquid will be drawninto the tank, through the pipe 25. \Vhen the liquid has accumulated to a considerable extent in the tank, the float 15 will rise, and the valve16 will close the suction pipe 19, thereby preventing liquid in the pipe 3 from being drawn out through the suction pipe:

By means of the handle 39, the connection 36 and the arms 34 and 35, the valves 40 and 21 may be set in such a way that the curved passage 23 in the valve 21 will establish communication between the air inlet 22 and that portion-of the pipe 19 which leads from the casing 20 to the tank 3, the lower portion of the pipe 19 being closed ofi so that there is no suction upon the tank.

It will be obvious that air now is adriiitted to the tank by way of the inlet 22, the pas-v the dispensing hose 29, it" being possible to control the amount of liquid dispensed by manipulating the Valve 28, the quantity of liquid supplied being determined by an inspection of the graduations 9 on the trans-. parent shell 6 of the tank 3. v

Having thus described the invention, what is claimed is In a device of the class described, a tank; a source of liquid supply; a dispensing outlet; a first valve establishing communication between the source and the tank, and between the tank and the outlet, at different times; a source of suction supply for the tank; an air inlet; a second valve establishing communication between the source of suction supply and the tank, and between the air inlet and'the tank, at different times a third valve cooperating with the source of-suction supply to open and close the GEORGE E. FRIESEN.
